IMPROVEMENT IN APPARATUS FOR COOLING STORAGE-ROOMS.

Specification forming part of Letters Patent No. 140,792, dated July 15,1873; application filed May 5, 1873.

To all whom it may concern:

Be it known that I, JoHN RING, of St. Louis, St. Louis county, Missouri,have invented an Improvement in Apparatus for Ooolin g Storage-Rooms,&c., of which the following is a specification:

My improvement consists in the combination, with a room or chamber, of acooling apparatus, consisting of an ice-chamber or tank havingice-supporting timbers arranged between the coils of a serpentinepipec'ommunicating with the room or chamber, the ice-tank being providedwith an overflow-pipe located above the level of the top of theserpentine pipe and below the level of the top of the ice-supportingtimbers, so that the serpentine pipe or air-tube is kept immersed incold water, while the ice is kept from contact with the water, andthereby prevented from melting too rapidly.

In the drawings, Figure 1 is an interior perspective view of the ice andstorage rooms, one wall being removed to exhibit the improvement. Fig. 2is a vertical section transverse to the main lengths of thecooling-pipe.

A is the ice-room. B is the storage-room. The walls of these rooms mayhave a lining, a and b, of saw-dust or other substance to check thepassage of heat from without. The room or tank A has a water-tightfloor, G,

I above which are shown timbers D, between which and the floor the waterhas free flow,

so as to reach the outflow-pipe E, which is below the level of the topof the timbers D. The timbers D are for the purpose of supporting aquantity of ice, which, by melting, supplies the cold water in whichis'immersed the continuous serpentine pipe F, laid backward and forwardfrom side to side of the room between or beneath the supporting-timbersD. One end of the pipe 13 is connected with a blower, G, in the room Bor elsewhere, and theother end, f, of the pipe has free communicationwith the room B, preferably in such a position as to cause a circulationin the room, by causing the entering air to traverse the room beforeagain entering the blower G. The blower may be arranged to cause acurrent of air in either direction, either by suction or by pressure. Itis preferable that the outflowing air should be taken from the upperpart of the room B, as the warmer air would seek that position. Theice-room or tank may be located directly above the room B, as shown, orat a distance therefrom, and the blower may be placed in the room B orelsewhere, if more convenient for motive power, the connection with theroom B and serpentine pipe being made by inlet and outlet pipes from theblower.

The operationof the apparatus is as follows: A quantity of ice beingplaced on the supports D in the room A, soon causes the pipe F to besurrounded by cold air, and as the ice melts water takes the place ofthe air until it reaches the level of the overflow-pipe E, which isabove the level of the top of the pipe, and below that of the top of thesup-' ports D. The blower causes a current of air to pass through thepipe F, the air being cooled in its passage through the pipe, and beingcarried back to the chamber B, from whence it had been drawn or forced.

The fan may act by suction upon the air in the pipe, or be arranged toforce the air through it by pressure, the end gained being the same, tocause air from the room B to flow through the cooling-pipe and return tothe room B. I

In hot weather there are certain industrial pursuits which cannot becarried on without artificial cooling of the rooms where the goods aremanipulated or stored; but to cool air at the normal temperature down tothe required degree consumes so large an amount -of ice as to render theoperation very expensive; but by taking the air from the cold room andextracting from it a small amount of heat, it is reduced to the requiredtemperature without much expenditure of ice, or of power in inducing theair-current, and without the use of any great length of cooling-pipe,such as would be required in cooling a considerable body of air--say 50Fahrenheit-the air, from the nature of the case, being brought to alower temperature every circuit it makes from the room B through thecooling-pipes and back again into the room B, from whence the blowertakes it.

I claim as my invention- In combination with the chamber B, the coolingapparatus, consisting of the ice-chamher or tank A, havingice-supporting timbers D arran gedbetween the coils of the serpentinepipe F, and provided with the overflow-pipe E, located above the levelof the top of the pipe F, and below the level of the top of the timbersD,'s0 that the pipe F is kept immersed in the cold water dripping fromthe ice as it melts While the ice is kept from contact with the Water,and thereby prevented from melting too rapidly, all as herein shown anddescribed.

JOHN RING.
